It generally refers to all structural alloy used in high-temperature applications, including heat resistant steel, high temperature alloy, refractory metal alloy, titanium alloy and high-temperature aluminum alloy. In the early stage of the development of high temperature alloy in China, people tend to translate high temperature alloy into heat resistant alloy, such as Nimonic alloy into Nimonic heat resistant alloy. Due to the continuous development of science and technology, people use more accurate names to classify alloy for high temperature applications, such as heat resistant titanium alloy, heat-resistant aluminum alloy, etc., and generally do not use the name heat resistant alloy.
